Struct HistoryPolicy 

pub struct HistoryPolicy { /* private fields */ }

History decisions for an external, host-owned graph frontier. The host supplies the shortest commit distance from wanted roots (starting at one) and persists deduplication, exclusions and work budgets outside this value.

Implementations

impl HistoryPolicy

pub const fn boundary_probe() -> Self

Measure distances to existing client boundaries without crossing them. A host only needs commit-parent and tag-target edges during this probe.

pub const fn follows_parents(self, depth: u32, client_boundary: bool) -> bool

pub const fn parent_depth(self, depth: u32) -> u32
